Marthe finds inspiration in comic books, skate culture, his friends, gentiane liquor, architecture, Dürher & Piranesi engravings, volcanology, old advertising posters, the NBA championship, spray paint, Corsica, his fat cat, cooking dishes, his drumkit, hiphop, rock'n'roll, and it is above all by constant fear of monotony that he diversifies his practice in order to continuously enrich his graphic universe."
